n the experiment "Molar mass of volatile liquid", the pressure of the gas inside a flask was the same as atmosphere, and the temperature was identical to the boiling water temperature of water bath. How did you measure the volume of the gas inside the flask?

When 225mg of anthracene, c14h10(s), was burned in a bomb calorimeter the temperature rose by 1.75k. calculate the calorimeter constant. by how much will the temperature rise when 125mg of phenol, c6h5oh(s), is burned in the calorimeter under the same conditions? (δch< (c14h10,s)=–7061 kj mol−1.)
